【摘要】：我國是電纜生產(chǎn)制造大國,目前絕大部分的高壓電纜都是采用交聯(lián)聚乙烯絕緣電纜。截止到2016年國家電網(wǎng)公司發(fā)布的最新信息表明,我國對6~500kV電纜線需求量大約90萬km。面對日益增長的電力行業(yè)的發(fā)展和對交聯(lián)聚乙烯絕緣電纜的巨大需求,工業(yè)化批量生產(chǎn)也達(dá)到了繁盛時期,但我國并是不電纜制造強(qiáng)國,高端特種電纜制造不出來、低端產(chǎn)品質(zhì)量水平不高、消耗大。造成這一現(xiàn)象的主要原因之一是因?yàn)樵陔娎|生產(chǎn)中只實(shí)現(xiàn)了底層自動化控制,但底層生產(chǎn)數(shù)據(jù)沒有收集與保存,更無法實(shí)現(xiàn)上層的集中管理與監(jiān)控,因此無法在線監(jiān)控生產(chǎn)質(zhì)量,只能依靠生產(chǎn)后抽樣、檢驗(yàn)。近年來隨著網(wǎng)絡(luò)技術(shù)發(fā)展的日新月異及監(jiān)控系統(tǒng)在企業(yè)生產(chǎn)和管理過程中的重要地位,建立一套交聯(lián)電纜生產(chǎn)線智能監(jiān)控系統(tǒng),對企業(yè)交聯(lián)電纜生產(chǎn)過程進(jìn)行實(shí)時、連續(xù)的監(jiān)測,不僅可以盡早發(fā)現(xiàn)問題并及時處理解決,而且這對交聯(lián)電纜生產(chǎn)的安全穩(wěn)定和提高生產(chǎn)效率都有著極其重要的意義。本文開展的主要工作包括:(1)交聯(lián)電纜生產(chǎn)過程包括拉絲、絞絲、絕緣、屏蔽、成纜、護(hù)套等多道工序,本文選取其中較為重要、復(fù)雜的絕緣工序作為研究對象,針對其交聯(lián)管設(shè)備溫度控制問題展開研究,分析了不同加熱區(qū)域的溫度變化的特性,建立了溫度控制對象的數(shù)學(xué)模型。(2)提出了基于模糊自整定PID的交聯(lián)溫度控制方法,并采用前述工作中建立的溫度控制對象數(shù)學(xué)模型對所提出方法進(jìn)行了仿真驗(yàn)證,實(shí)驗(yàn)結(jié)果顯示所提方法比現(xiàn)場采用的經(jīng)典PID控制方法更為優(yōu)越。(3)根據(jù)工業(yè)現(xiàn)場溫度控制設(shè)備技術(shù)要求,將所提出的基于模糊自整定PID的交聯(lián)溫度控制方法進(jìn)行PLC編程實(shí)現(xiàn),為應(yīng)用實(shí)踐打下基礎(chǔ)。(4)運(yùn)用組態(tài)王開發(fā)監(jiān)控系統(tǒng)軟件對交聯(lián)電纜生產(chǎn)過程進(jìn)行了HMI設(shè)計,并對交聯(lián)電纜生產(chǎn)過程監(jiān)控系統(tǒng)進(jìn)行了運(yùn)行與測試,達(dá)到了預(yù)期的良好效果。
[Abstract]:China is a large country in cable production and manufacture. At present, most of the high-voltage cables use XLPE insulated cables. As of 2016, the latest information released by the State Grid Corporation shows that. The demand for 610kV cable lines in China is about 900,000 kms.In the face of the increasing development of the power industry and the huge demand for XLPE insulated cables, the industrial mass production has also reached a prosperous period, but China is also a powerful country in the manufacture of non-cable cables. High-end special cable can not be manufactured, the quality of low-end products is not high, and the consumption is large. One of the main reasons for this phenomenon is that only the automation control of the bottom layer is realized in cable production, but the bottom production data are not collected and preserved. It is also impossible to realize centralized management and monitoring in the upper layer, so it is impossible to monitor the quality of production online, and can only rely on sampling after production. In recent years, with the rapid development of network technology and the important position of monitoring system in the process of production and management of enterprises, an intelligent monitoring system for cross-linking cable production line is established to carry out real-time production of cross-linked cables in enterprises. Continuous monitoring can not only detect problems as early as possible and solve them in a timely manner. And this is of great significance to the safety and stability of the production of cross-linked cables and to the improvement of production efficiency. The main work carried out in this paper includes drawing, twisting, insulation, shielding and cable formation of cross-linked cables. In this paper, the more important and complex insulation process is selected as the research object, and the temperature control problem of the cross-linking pipe equipment is studied, and the characteristics of temperature change in different heating regions are analyzed. The mathematical model of temperature control object is established. (2) A cross-linking temperature control method based on fuzzy self-tuning PID is proposed, and the method is simulated by using the mathematical model of temperature control object established in the previous work. The experimental results show that the proposed method is superior to the classical PID control method used in the field. According to the technical requirements of the industrial field temperature control equipment, the proposed cross-linking temperature control method based on fuzzy self-tuning PID is implemented by PLC programming. In order to lay the foundation for the practice, the author uses Kingview to develop the monitoring system software to design the HMI for the production process of the cross-linked cable, and runs and tests the monitoring system of the production process of the cross-linked cable, and achieves the expected good effect.
